Smithfield Green Waste Disposal Services

Our Green Waste Disposal Process

Smithfield’s Green Waste Collection Schedule, Accepted Materials, and Disposal Protocols

Green waste disposal in Smithfield is governed by a structured municipal collection program designed to ensure environmental compliance and efficient service. Weekly curbside pickup occurs every Thursday from April through November, with residents required to use biodegradable paper bags or reusable bins (32-gallon maximum) for leaves, grass clippings, and brush under 4 feet in length. The use of plastic bags and disposal of branches over 4 inches in diameter are strictly prohibited. All green waste must be placed curbside by 7:00 AM on collection day. For larger debris or off-schedule disposal, residents may utilize the town’s designated drop-off facility, which operates Monday through Saturday, 8:00 AM to 3:00 PM. Adherence to these protocols helps prevent stormwater contamination and supports Smithfield’s MS4 permit obligations under the Clean Water Act.

Soil Series and Drainage Considerations for Green Waste in Smithfield

Smithfield’s landscape is characterized by Inceptisols and Udults, with prevalent soil series such as Sutton fine sandy loam and Ridgebury fine sandy loam, as identified by the USDA Web Soil Survey. These soils are moderately acidic (pH 5.5-6.5) and often poorly drained, with seasonal water tables at 12-18 inches. When managing green waste, it is essential to avoid stockpiling debris in low-lying or wetland-adjacent areas to prevent nutrient runoff and soil compaction. Composting on-site should incorporate 2-3 inches of organic matter tilled to a 6-inch depth, and soil testing is recommended every 2-3 years through the University of Rhode Island Cooperative Extension (typical cost: $15-25). Key soil management practices include:

• Avoiding green waste accumulation within 25 feet of wetlands
• Using lime to adjust pH below 6.0
• Ensuring compost piles are located on well-drained, upland sites

Environmental Compliance: Wetland Buffers and Stormwater Protection in Smithfield

Smithfield’s proximity to the Woonasquatucket River, Stillwater Reservoir, and numerous wetlands necessitates strict adherence to environmental regulations for green waste disposal. The town enforces a 25-foot no-disturbance buffer from all wetlands and water bodies, in accordance with the Rhode Island Environmental Rights Act and local ordinances. The MS4 permit, administered by the Rhode Island Department of Environmental Management, prohibits the placement of yard debris in or near storm drains to prevent nutrient and sediment pollution. Residents must:

• Maintain a 25-foot buffer from wetlands for all disposal and composting activities
• Never deposit clippings or leaves in stormwater catch basins
• Use only approved containers for curbside collection
• Report illegal dumping to the town’s code enforcement office
